IMPROVEMENT IN HQRSESHOES.

Specification forming part of Letters Patent No. 13?,128, dated March 25, 1873.

To all whom it may concern:

Be it known that I, ISAAC DE Mora, of Gannonsville, Delaware county and State of New York, have invented a new and useful manner of fastening the calks to the shoe.

I am aware that detachable calks have been made before, and that in themselves they possess no novelty as such; but the manner of fastening them to the shoe has hitherto been objectionable. Either the shoe has been weakened by the manner of fastening, or the calk isliable to become displaced by alateral twist or strain.

In the accompanying drawing, Figure l is a View of the calk side of a horseshoe constructed according to my invention. Fig. 2 is a cross-section of Fig. 1 taken on the line w :10. Fig. 3 is a view of one of the calks detached.

Similar letters of reference indicate correspondin g parts.

A is the shoe. B is the toe-calk, and G O the heel-calks. D is a lip turned up from the shoe at the toe and heel, to which the calk is doweled, as seen in Fig. 2. These lips are turned so as to form angles with the face of E. F is the dowel.

dowel and a single screw is all that is required the shoe, and the calks are fitted to the an= gles and are doweled to the lips, while the other branch of the calk is fitted to the face of the shoe, and fastened thereto with a screw, With the lip D a single to hold the calk firmly to its'place.

It will be noticed that but one hole is made in the shoe for each calk. The hole for the dowel-pin consequently does not weaken the shoe, but,,placed as it is through the lip; and at a distance from the face of the shoe, it prevents the calk from tipping or twisting out of .place much more effectually than when entering the shoe, as is usual with detach able calks. Thelip D itself forms a very material support to the calk, keeping it in place and strengthening it. A

The calks are made of hardened steel, and

may be duplicated, so that new calks may be
